Cov ntsuas hluav taws xob yog qhov qub, tab sis koj puas tau xav paub tias "cov khoom siv txheem" siv los ntsuas lawv li cas tau txais nws "check-up"? Tshwj xeeb tshaj yog nrog kev siv ntau megawatt-theem supercharging chaw nres tsheb rau lub zog tshiab tsheb, yuav ua li cas kom tiav tag nrho - lub zog ntsuas hluav taws xob, siv 1000 kilowatt- teev ib teev, ua tiav?
Puas yog lub ntsuas hluav taws xob ntsuas ntsuas ib txwm ua raws li qhov tseeb load? Hauv kev ntsuas hluav taws xob, peb ntse siv "virtual load" thev naus laus zis los daws qhov teeb meem no.
Puas yog tag nrho cov ntsuas hluav taws xob ntsuas ntsuas tau ua nrog lub nra tiag?
Xaus: Tsis tas li.
Thaum lub hauv paus ntsiab lus, kev tsav tsheb tiag tiag nrog lub ntsuas hluav taws xob yog qhov kev sim siab tshaj plaws, hauv kev xyaum, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj hluav taws xob siab, siab tam sim no, lossis qhov tseeb siab, "virtual load method" yog txoj hauv kev loj.
Rau UBS Electronics megawatt flash charging pawg hluav taws xob ntsuas hluav taws xob (1000V / 1000A) tau hais los saum no, yog tias ua tiav qhov kev sib tw tiag tiag:
- Hwj chim: P=U*I=1000V*1000A=1,000,000W=1MW
-
Kev siv hluav taws xob: Kev khiav ntawm tag nrho cov load rau 1 teev tiag tiag siv 1000 kWh ntawm hluav taws xob thiab yuav tsum muaj qhov txias txias.
Qhov no yog qhov tsis tshua muaj nyiaj txiag thiab nyuaj rau kev siv hauv chav kuaj lossis thaj chaw calibration. Yog li ntawd, rau ob qho tib si AC thiab DC fais fab ntsuas, "virtual load verification method" (tseem hu ua "standard meter method" los yog "power supply method") yog lub hauv paus ntsiab lus los daws qhov teeb meem ntawm siab -power verification.
Real Load Test vs. Virtual Load Test: Dab tsi yog qhov txawv?
Ob txoj hauv kev tuaj yeem muab piv rau "hnyav tus kheej":
- Real Load Test: Qhov no yog sib npaug rau kev siv tus qauv ntawm qhov hnyav uas paub qhov hnyav (qhov tseeb lub cev hnyav) los nias rau ntawm qhov ntsuas (lub ntsuas hluav taws xob) kom pom tias qhov ntsuas qhov tseeb.
- Virtual Load Test: Qhov no sib npaug rau simulating lub teeb liab "dag" load los ntawm circuitry, qhia lub ntsuas hluav taws xob tias "hluav taws xob tam sim no tau siv," tab sis qhov tseeb, tsis muaj hluav taws xob ntau.
Qhov tseeb Load Verification Method
Txoj kev no siv cov khoom siv lub cev tiag tiag (xws li resistors, inductors, thiab capacitors) raws li cov khoom thauj:
1. Lub hauv paus ntsiab lus: Lub ntsuas hluav taws xob tus qauv thiab lub ntsuas hluav taws xob nyob rau hauv kev sim tau txuas nrog hauv cov kab hauv tib lub sijhawm thauj khoom, tso cai rau lawv ua haujlwm nyob rau hauv tib qhov hluav taws xob thiab tam sim no. Qhov sib txawv ntawm lawv cov ntawv nyeem yog tom qab ntawd muab piv.
2. Application Scenarios: Feem ntau yog siv rau qhov yooj yim ntawm - qhov chaw pov thawj, kuaj cov laus induction- hom ntsuas hluav taws xob, lossis hauv cov chaw kuaj me me uas tsis muaj siab - cov khoom siv hluav taws xob muaj tseeb.
Virtual Load Verification Method
Nov yog txoj hauv kev tseem ceeb rau kev ntsuas hluav taws xob niaj hnub, tshwj xeeb tshaj yog rau hluav taws xob thiab DC hluav taws xob ntsuas:
1. Lub hauv paus ntsiab lus: Siv lub programmable fais fab mov, qhov hluav taws xob thiab tam sim no yog muab rau nws tus kheej. Lub voj voog hluav taws xob thiab lub voj voog tam sim no yog lub cev sib cais (lub voj voog hluav taws xob muaj qhov tsis tshua muaj tam sim no, thiab lub voj tam sim no muaj qhov tsis tshua muaj hluav taws xob tsawg). Cov hluav taws xob hluav taws xob zoo simulate ntau yam kev ua haujlwm uas yuav tsum tau ua rau kev ua haujlwm ib txwm muaj ntawm lub ntsuas hluav taws xob (xws li lub zog sib txawv thiab qhov sib txawv tam sim no).
2. Daim ntawv thov Scenarios: Yuav luag tag nrho cov chav kuaj puv -kev ua pov thawj, kev tshuaj xyuas lub Hoobkas, thiab siab - qhov tseeb ntawm - qhov chaw calibration.
Hauv - sib piv qhov tob ntawm qhov zoo thiab qhov tsis zoo ntawm ob txoj kev pov thawj
Rau kev sib piv meej, cov lus hauv qab no tau muab tso ua ke:
| Sib piv Dimension | Tiag -Load Calibration Method | Virtual -Load Calibration Method |
|---|---|---|
| Kev siv hluav taws xob | Siab heev. Yuav tsum hloov hluav taws xob hluav taws xob mus rau hauv thermal lossis mechanical zog, uas yog lub zog- siv zog thiab ua rau muaj cua sov loj heev. | Tsawg heev. Tsuas yog siv lub zog me me ntawm lub cuab yeej nws tus kheej, lub zog -nrawm thiab eco- tus phooj ywg. |
| Khoom Loj | Loj thiab hnyav. High tam sim no yuav tsum muaj lub txhab nyiaj loj loj (zoo ib yam li lub qhov cub hluav taws xob loj). | Compact thiab lub teeb yuag. Tsim los ntawm cov khoom siv hluav taws xob, yooj yim ua rau hauv daim ntawv portable. |
| Ntsuas qhov tseeb | Tsawg heev. Zoo heev cuam tshuam los ntawm load tivthaiv kev laus thiab kub drift, nyuaj rau kho. | Siab heev. Ua tiav qhov tseeb ntawm 0.05% lossis siab dua nrog zoo linearity. |
| Kev Pabcuam Ntau | Txwv tsis pub. Yooj yim kom raug simulate me me tam sim no (piv txwv li, pib tam sim no) lossis huab cua dhau heev. | Tag nrho - ntau yam. Yooj yim npog tag nrho ntawm qhov pib tam sim no (0.4% Ib) mus rau qhov siab tshaj plaws tam sim no. |
| Kev nyab xeeb | Tsawg heev. Muaj kev pheej hmoo ntawm cua sov thiab luv luv Circuit Court nyob rau hauv siab tam sim no, ua rau muaj kev nyab xeeb. | Kwv tij siab. Kev sib cais tswj thiab hluav taws xob circuits nrog ua tiav kev tiv thaiv mechanisms. |

Vim li cas txoj kev thauj khoom virtual yog qhov tseeb dua?
Hauv txoj kev thauj khoom tiag tiag, yog tias lub kauj tam sim no muaj qhov tsis kam, qhov hluav taws xob poob yuav tshwm sim, ua rau muaj kev hloov pauv ntawm qhov hluav taws xob hla lub kauj hluav taws xob, yog li qhia "qhov yuam kev ntxiv." Hauv txoj kev thauj khoom virtual, qhov hluav taws xob thiab cov voj voog tam sim no muaj kev ywj pheej thiab tsis cuam tshuam rau ib leeg, yog li ntawd tsis muaj qhov yuam kev ntxiv, thiab cov txiaj ntsig kev ntsuas tau ze dua rau qhov tseeb qhov tseeb.
Vim li cas txoj kev thauj khoom virtual tuaj yeem ntsuas megawatt -theem fais fab?
Lub virtual load calibration ntaus ntawv (tus qauv qhov chaw) sab hauv siv siab - fais fab transistors los yog IGBT modules invert DC fais fab mus rau AC waveform, los yog ncaj qha ua DC tswj. Tsis zoo li txoj kev thauj khoom tiag tiag, nws tsis tas yuav dissipate 1MW ntawm hluav taws xob hluav taws xob raws li cua sov; Hloov chaw, los ntawm kev kaw- voj tswj, nws tuaj yeem simulate cov yam ntxwv hluav taws xob ntawm 1MW nrog tsuas yog me me ntawm hluav taws xob hluav taws xob.
Cov ntsiab lus
Rov qab mus rau lo lus nug thawj zaug: Puas yog tag nrho cov ntsuas hluav taws xob kuaj xyuas raws li qhov tseeb ntawm cov khoom thauj?
Tsis yog. Tsuas yog qee qhov yooj yim ntawm - qhov kev txheeb xyuas qhov chaw lossis kev sim ntawm cov meters siab dua, kev ntsuas hluav taws xob niaj hnub (tshwj xeeb tshaj yog siab -voltage, siab -tam sim no DC supercharging meters) yuav luag 100% siv txoj kev tshawb xyuas virtual.
Thaum txoj kev thauj khoom tiag tiag yog "qhov tseeb," nws raug txwv los ntawm kev siv lub zog, qhov loj me, thiab qhov tseeb, thiab tau maj mam raug txiav tawm lossis tsuas yog siv los ua ib txoj hauv kev pabcuam xwb.
Txoj kev thauj khoom virtual siv cov thev naus laus zis thev naus laus zis kom ua tiav "lub cav me me rub lub nra loj," kom ntseeg tau qhov tseeb ntawm lub teb chaws metrological qauv thaum daws teeb meem kev siv hluav taws xob ntawm megawatt - qib superchargeing pawg pov thawj.
Lub sijhawm tom ntej koj pom tias lub ntsuas hluav taws xob me me ntawm lub chaw them nyiaj, paub tias tom qab nws yog "kev ntsuas kev ntxhov siab heev" uas simulates txhua yam kev ua haujlwm uas siv cov khoom siv hluav taws xob siab -tech.
